I knew Argyle Street well, some of my schoolfriends lived there. It has long gone I'm afraid. It was a small dead-end street off Park Street, opposite the main entrance to Colville's steel works. The main Glasgow-London railway line was at the end of the street, it was a large cul-de-sac really, with tenements on either side. One of the buildings was called Grieve's Land, my great-grandfather lived there.
If you tell me the name of your ancestor I'll check if the family were there in the 1911 street directory.
